The car had modified Benz engine. It was two cylinders spark ignition engine with power output of about 9 kW (12HP) at 1800RPM. It was situated above the driven rear axle, longwise with the cars axis.

The driver was situated on highened seat behind the steering wheel, while the passenger's seat was much lower on the frame, so his legs were sticking out under the car.

The gas tank had volume of 42 litres, while there was also another tank behind the driver for 15 liters of coolant.

The car was able to reach maximum speed of 82 km/h.

Von Liebig raced the car in numerous contests. He won the race Nice - La Turbie, and took second position in Salzburg-Linz-Vienna race. He later took part also in Paris-Vienna race.
